    Protein Summary

    Pfam Update: There is one other structure 1vkd, in that family, that is described thus in TOPSAN: Protein Summary The gene TM1225 from Thermotoga maritima encodes the NP_229030 protein from the DUF377 group (PF04041). The protein belongs to the glycosyl hydrolases 43 superfamily COG2152. The genomic neighborhood of TM1225 shows the presence (score 0.8) of a transcriptional regulator XylR-related (TM1224). SCOP classifies 1vkd in the all beta class, 5-bladed beta propeller fold, arabinase/levansucrase/invertase superfamily, TM1225-like family. 1vkd shows structural similarity (Dali Z=22) to many beta-xylosidases like 3cpn, 1yrz, 2exh, or 3c2u. Glycosyl hydrolases are a big and widespread family of enzymes that hydrolyse the glycosidic bonds between carbohydrates or between a carbohydrate and an aglycone moiety. On the basis of sequence and structural similarity, the glycoside hydrolase family belongs to the beta-fructosidase (furanosidase) family of glycosyl hydrolases [1]. The enzyme, most probably, acts on a furanoside residue (fructose, arabinose and ribose). So, solution of this should confirm that. There were certainly overlaps to the GH family when I ran jackhmmer.

     

    Target ID 393092 is a member of the  DUF377 (PF04041) Pfam family. Shown below are two representations of the monomer.
